Abstract

L'invention porte sur un dispositif de mesure optique (2) comprenant : un élément de correction (41) qui est un objet d'éclairage d'une lumière d'éclairage lorsqu'un procédé de correction du dispositif de mesure optique (2) et d'une sonde de mesure (3) est réalisé; une partie d'introduction (42a) dans laquelle une extrémité avant de la sonde de mesure (3) peut être introduite; une partie de réception (42b) qui communique avec la partie d'introduction (42a) et reçoit de manière mobile l'élément de correction (41) le long de la direction de pénétration de la partie d'introduction (42a); un élément de corps de boîtier (42) qui communique avec la partie de réception (42b), a une partie d'ouverture (42c) formée, laquelle retient au moins un composant d'une unité de commutateur (25) sur laquelle une force d'actionnement est appliquée, et est positionnée par rapport à l'unité de commutateur (25) d'une manière telle que la force d'actionnement est appliquée sur l'unité de commutateur (25) lorsque l'élément de correction (41) atteint un emplacement prescrit à l'intérieur de la partie de réception (42b) par la sonde de mesure (3) qui est introduite à partir de la partie d'introduction (42a); et une unité de contrôleur (27) qui réalise une commande qui commence le procédé de correction lorsqu'une alimentation électrique (21) est activée.
